One of the most prestigious champagne houses runs an informative tour, describing the champagne-making process and filling you in on champagne lore: Napoleon, a friend of Jean-Rémy Moët, used to stop by for thousands of bottles on his way to battle. The only time he didn’t take a supply was at Waterloo—and look what happened there. The basic tour includes a glass of champagne; more expensive tickets entitle you to more glasses.
